            or a pharmaceutically acceptable salt or ester thereof,             excluding the following compounds:

5,6,7,8-tetrahydro-7-methyl-N-[4-(phenylmethoxy)phenyl]-[1]benzothieno-[2,3-d]pyrimidin-amine, monohydrochloride;

5,6,7,8-tetrahydro-N-(4-methoxyphenyl)-7-methyl-[1]benzothieno[2,3-d]pyrimidin-4-amine, monohydrochloride;

N-(3,4-dimethylphenyl)-5,6,7,8-tetrahydro-7-methyl [1]benzothieno-[2,3-d]pyrimidin-4-amine.

The terms have the following meaning throughout:

The term “optionally substituted” means that the moiety so modified may have from none to up to at least the highest number of substituents indicated. The substituent may replace any H atom on the moiety so modified as long as the replacement is chemically possible and chemically stable. When there are two or more substituents on any moiety, each substituent is chosen independently of any other substituent and can, accordingly, be the same or different.

The terms “(C₁-C₃)alkyl” and “(C₁-C₆)alkyl” mean a linear or branched saturated hydrocarbon radical having from about 1 to about 3 or about 6 C atoms, respectively. Such groups include but are not limited to methyl, ethyl, n-propyl, isopropyl, and the like.

The term “(C₁-C₃)alkoxy” means a linear or branched saturated hydrocarbon radical having from about 1 to about 3 C atoms, said radical being attached to an O atom. The O atom is the point of attachment of the alkoxy substituent to the rest of the molecule. Such groups include but are not limited to methoxy, ethoxy, n-propoxy, isopropoxy, and the like.

The term “(C₁-C₃)alkoxy-phenyl” means a phenyl group bonded to the alkyl portion of an alkoxy group, as alkoxy is defined above. The phenyl group is bonded to any accessible primary or secondary C atom in the alkyl portion of the alkoxy-phenyl group, and the alkoxy-phenyl group is attached to the rest of the molecule through the O atom.

The term “(C₁-C₃)alkoxy-pyridyl” means a pyridyl group bonded to the alkyl portion of an alkoxy group, as alkoxy is defined above. The pyridyl group is bonded to any accessible primary or secondary C atom in the alkyl portion of the alkoxy-pyridyl group, and the alkoxy-pyridyl group is attached to the rest of the molecule through the O atom.

The term “O-phenyl” means a phenyl group bonded to an O atom. The O atom is the point of attachment of the group to the rest of the molecule.

The term “(C₂-C₆)alkenyl” means a linear or branched carbon group having from about 2 to about 6 C atoms wherein at least two adjacent C atoms in the alkenyl group are joined by a double bond, with the proviso that when a C atom is double bonded to one adjacent C atom, it must be single bonded to any other adjacent C atom. The alkenyl group is attached to the rest of the molecule through a single bond.

The term “(C₂-C₆)alkynyl” means a linear or branched carbon group having from about 2 to about 6 C atoms wherein there is at least one triple bond between two adjacent C atoms in the group with the proviso that when a C atom is triple bonded to one adjacent C atom, it must be single bonded to any other adjacent C atom. The alkynyl group is attached to the rest of the molecule through a single bond.

The term “halo” means Cl, Br, F or I.

When “(O)” is used in a chemical formula, it means an O atom that is double bonded to the atom to which it is attached, but is not further bonded to any other atom, for example, “C(O)” represents a carbonyl group.

The formulae “N[C₁-C₃)alkyl]₂”, “NR⁸R⁸”, “NR⁸⁻¹R⁸⁻¹” and “NR¹⁰R¹⁰” each means that each of the 2 possible groups attached to the N atom are selected independently from the other so that they may be the same or they may be different.

The term “a five membered heterocycle” means a ring made of 5 atoms, 1, 2 or 3 of which are N with the remaining atoms being C. The heterocycle is saturated, unsaturated or partially saturated. Five membered heterocycles include but are not limited to pyrrolyl, imidazolyl, pyrazolyl, pyrrolidinyl, pyrrolinyl, imidazolidinyl, imidazolinyl, pyrazolidinyl, pyrazolinyl, triazolyl, and the like. The heterocycle is attached to the rest of the molecule through a bond attached to the heterocycle at any position of the heterocyclic radical from which a H atom could conceptually have been removed to create the radical from its corresponding stand-alone molecule.

When a phenyl ring, pyridyl ring, or a five membered heterocycle is attached to the rest of the molecule, the bond to the rest of the molecule is attached to the radical at any position of the radical from which a H could conceptually have been removed to create the radical from its corresponding stand-alone molecule.

When prefixes such as (C₁-C₄) are used before substituents, they mean to indicate the respective number of carbon atoms, in this case 1 to 4.

A * symbol next to a bond denotes the point of attachment in the molecule.

Except for intermediates, chemically unstable compounds are less preferred in the context of the present invention. Chemically unstable here is meant to include conditions to which a compound is exposed when administered to a patient in need thereof, such as acidic or basic conditions of the gastrointestinal tract. For example, a chemically unstable compound would be one where two nitrogen or oxygen substituents are bonded to a single aliphatic carbon atom. Another example of a chemically unstable compound would be one where an alkoxy group is bonded to the unsaturated carbon of an alkene to form an enol ether. Furthermore, an aliphatic carbon atom attached to oxygen may not also bear a chloro, bromo or iodo substituent, and when any alkyl group is attached to O, S, or N, and bears a hydroxyl substituent, then the hydroxyl substituent is separated by at least two carbon atoms from the O, S, or N to which the alkyl group is attached.

Asymmetry, i.e., where a compound's mirror image cannot be super-imposed on the compound, may be present in a compound of Formula I due to the inherent structure of the molecule. Examples of such asymmetric molecules include certain allenes. The compounds of this invention may also contain one or more asymmetric centers, depending upon the location and nature of the various substituents selected. A molecule with a single asymmetric center may be a mixture of enantiomers (R,S), or may be a single (R) or (S) enantiomer. A molecule with more than one asymmetric center may be a mixture of diastereomers, or may be a single diastereomer. Additionally, a compound may exhibit asymmetry due to restricted rotation about a given bond, for example, the central bond adjoining two substituted aromatic rings of the specified compounds. It is intended that all such configurations and conformations (including enantiomers, diastereomers, and other optical isomers) are included within the scope of the present invention. Separated, pure or partially purified stereoisomers of the compounds of Formula I are each included within the scope of the present invention. Preferred compounds are those with the absolute configuration or conformation which produces the more desirable biological activity.

Pharmaceutically acceptable salts of the compounds of this invention are also within the scope of this invention. The term “pharmaceutically acceptable salt” refers to an inorganic or organic salt of a compound of the present invention that has properties acceptable for therapeutic use. For example, see S. M. Berge, et al. “Pharmaceutical Salts,” J. Pharm. Sci. 1977, 66, 1-19.

Representative salts of the compounds of this invention include the conventional non-toxic salts and the quaternary ammonium salts that are formed, for example, from inorganic or organic acids or bases by means well known in the art. For example, such acid addition salts include acetate, adipate, alginate, ascorbate, aspartate, benzoate, benzenesulfonate, bisulfate, butyrate, citrate, camphorate, camphorsulfonate, cinnamate, cyclopentanepropionate, digluconate, dodecylsulfate, ethanesulfonate, fumarate, glucoheptanoate, glycerophosphate, hemisulfate, heptanoate, hexanoate, hydrochloride, hydrobromide, hydroiodide, 2-hydroxyethanesulfonate, itaconate, lactate, maleate, mandelate, methanesulfonate, 2-naphthalenesulfonate, nicotinate, nitrate, oxalate, pamoate, pectinate, persulfate, 3-phenylpropionate, picrate, pivalate, propionate, succinate, sulfonate, tartrate, thiocyanate, tosylate, sulfate, and undecanoate. The term acid addition salts also comprises the hydrates and the solvent addition forms which the compounds of this invention are able to form. Examples of such forms are, for example, hydrates, alcoholates and the like.

Base salts include alkali metal salts such as potassium and sodium salts, alkaline earth metal salts such as calcium and magnesium salts, and ammonium salts with organic bases such as dicyclohexylamine and N-methyl-D-glucamine. Additionally, basic nitrogen containing groups may be quaternized with such agents as lower alkyl halides such as methyl, ethyl, propyl, and butyl chlorides, bromides and iodides; dialkyl sulfates including dimethyl, diethyl, and dibutyl sulfate; and diamyl sulfates, long chain halides such as decyl, lauryl, myristyl and strearyl chlorides, bromides and iodides, aralkyl halides including benzyl and phenethyl bromides, and others.

The esters of appropriate compounds of this invention are pharmaceutically acceptable esters such as (C₁-C₆)alkyl esters, including methyl, ethyl, propyl, isopropyl, butyl, isobutyl or pentyl esters, and the like. Additional esters such as (C₁-C₆)alkyl-phenyl may be used, although methyl ester is preferred.

Unless the context clearly indicates to the contrary, whenever the term “compounds of this invention,” “a compound of the present invention”, and the like, are used herein, they are intended to include the chemically feasible pharmaceutically acceptable salts and/or esters as well as all stereoisomeric forms of the referenced compounds.

Chem. 1994, 47(10), 1833-1842.; Tetrahedron 1999, 55, 11095-11108.), each of which is incorporated herein by reference. Cyclohexanone (1) is coupled with an appropriate cyanoacetic ester (2) in the presence of elemental sulfur and a base such as morpholine, preferably at room temperature, to yield the aminothiophene ester of formula (3) according to the procedure of Gewald, J. Heterocyclic Chem., 1999, 36, 333-345, which is incorporated herein by reference. The aminothiophene ester (3) is then converted to a compound of formula (4) by reaction with a formamide-containing reagent such as neat formamide, or formamidine acetate, in a polar solvent such as DMF, with heat, preferably to 100° C. or above. Heating the compound of formula (4) with a reagent such as phosphorous oxychloride provides compound (5). Finally, compound (5) may be reacted with a variety of substituted anilines (6), each of which is readily available or can be synthesized by means well known in the art, in the presence of a catalytic amount of concentrated acid, such as HCl, and a protic solvent, such as ethanol, to yield a compound of Formula I.

Reaction Scheme 2 outlines the synthesis of certain compounds of Formula I where one R is H (not shown) and the other R is (C₁-C₆)alkyl substituted with OH or halo, or with C(O)R⁶ where R⁶ is NR⁸R⁸.

The starting material (Ia), where one R is H (not shown) and the other R is (CH₂)_(m)C(O)O(C₁-C₃)alkoxy, and m is 0, 1, 2, 3, 4, 5 or 6 may be made according to Reaction Scheme 1. Compound (la) is either saponified to its corresponding carboxylic acid under basic conditions (such as 1N NaOH in an appropriate solvent) and subsequently coupled with 1,1′-carbonyldiimidazole and an amine (HNR⁸R⁸) to yield the amide (Ib), or alternatively, (Ia) is converted to the amide (Ib) by a Weinreb (Tetrahedron Lett. 1981, 22 (39), 3815-3818) amidation with a reagent such as trimethyl aluminum and a nucleophilic amine such as piperidine (as shown in Example 3). If desired, (Ib) is reduced to its corresponding amine (Ie) in one step via a reducing reagent such as DIBAL-H in a protic solvent such as THF. Compound (Ia) may also be reduced to its corresponding alcohol (Ic) with a reducing agent such as DIBAL-H in a protic solvent such as THF. The alcohol (Ic) may be further transformed into the bromoalkyl (Id) by bromination with a reagent such as CBr₄ in the presence of PPh₃. Reaction of the bromoalkyl (Id) with an amine (NHR⁸R⁸) such as piperidine (such as in Example 4) also yields compounds of formula (Ie).

Reaction Scheme 3 outlines the synthesis of the compounds of Formula I where one R is H (not shown) and the other R is (C₁-C₆)alkyl R⁷ and R⁷ is NH S(O)₂R⁹ (If), or NH(C(O)NR⁸R⁸ (Ig).

Compound (Ie′) (where R⁸ of (Ie)'s NR⁸R⁸ group is H in both instances) of Reaction Scheme 2 is reacted with an amine HNR⁸R⁸ in the presence of a coupling reagent such as 1,1′-carbonyldiimidazole, or (Ie) is reacted with an isocyanate R⁸N═C═O. Compounds of formula (Ie) can also be reacted with sulfonyl chlorides and a mild base such as TEA in a solvent such as CH₂Cl₂ to yield the compounds of Formula (Ig).

Reaction Scheme 4 outlines the synthesis of the compounds of Formula (Ih), and of Formula (Ii) where one R is H (not shown) and the other R is (CH₂)_(m)C(O)R⁶, m is 0,1,2,3,4,5 or 6, and R⁶ is (C₁-C₆)alkyl, pyridyl or phenyl.

In one pathway of Reaction Scheme 4, the compound of formula (Ia), as previously described above in Reaction Scheme 2, is reacted in an inert solvent such as THF, with an alkyl or aryl Grignard reagent of formula R⁶MgX, where R⁶ is a (C₁-C₆)alkyl, phenyl or pyridyl group and X is Br, Cl, or I, to provide a ketone of formula (Ii). In the alternative pathway, the formula (Ia) compound is first saponified to the corresponding carboxylic acid, the convert to an acid chloride of formula (Ih), which is then subjected to the same Grignard reaction conditions to provide compound (Ii).

The compounds of the present invention can be administered with pharmaceutically-acceptable carriers well known in the art using any effective conventional dosage unit forms formulated as immediate, slow or timed release preparations, including, for example, the following.

For oral administration, the compounds can be formulated into solid or liquid preparations such as capsules, pills, tablets, troches, lozenges, melts, powders, solutions, suspensions, or emulsions, and may be prepared according to methods known to the art for the manufacture of pharmaceutical compositions. The solid unit dosage forms can be a capsule which can be of the ordinary hard- or soft-shelled gelatin type containing, for example, surfactants, lubricants, and inert fillers such as lactose, sucrose, calcium phosphate, and corn starch.

In another embodiment, the compounds of this invention may be tableted with conventional tablet bases such as lactose, sucrose and cornstarch in combination with binders such as acacia, corn starch or gelatin, disintegrating agents intended to assist the break-up and dissolution of the tablet following administration such as potato starch, alginic acid, corn starch, and guar gum, gum tragacanth, acacia, lubricants intended to improve the flow of tablet granulation and to prevent the adhesion of tablet material to the surfaces of the tablet dies and punches, for example talc, stearic acid, or magnesium, calcium or zinc stearate, dyes, coloring agents, and flavoring agents such as peppermint, oil of wintergreen, or cherry flavoring, intended to enhance the aesthetic qualities of the tablets and make them more acceptable to the patient.

Dispersible powders and granules are suitable for the preparation of an aqueous suspension. They provide the active ingredient in admixture with a dispersing or wetting agent, a suspending agent and one or more preservatives. Suitable dispersing or wetting agents and suspending agents are exemplified by those already mentioned above. Additional excipients, for example those sweetening, flavoring and coloring agents described above, may also be present.

The pharmaceutical compositions of this invention may also be in the form of oil-in-water emulsions. The oily phase may be a vegetable oil such as liquid paraffin or a mixture of vegetable oils. Suitable emulsifying agents may be (1) naturally occurring gums such as gum acacia and gum tragacanth, (2) naturally occurring phosphatides such as soy bean and lecithin, (3) esters or partial esters derived form fatty acids and hexitol anhydrides, for example, sorbitan monooleate, (4) condensation products of said partial esters with ethylene oxide, for example, polyoxyethylene sorbitan monooleate. The emulsions may also contain sweetening and flavoring agents.

Oily suspensions may be formulated by suspending the active ingredient in a vegetable oil such as, for example, arachis oil, olive oil, sesame oil or coconut oil, or in a mineral oil such as liquid paraffin. The oily suspensions may contain a thickening agent such as, for example, beeswax, hard paraffin, or cetyl alcohol. The suspensions may also contain one or more preservatives, for example, ethyl or n-propyl p-hydroxybenzoate; one or more coloring agents; one or more flavoring agents; and one or more sweetening agents such as sucrose or saccharin.

The compounds of this invention may also be administered parenterally, that is, subcutaneously, intravenously, intraocularly, intrasynovially, intramuscularly, or interperitoneally, as injectable dosages of the compound in a physiologically acceptable diluent with a pharmaceutical carrier which can be a sterile liquid or mixture of liquids such as water, saline, aqueous dextrose and related sugar solutions, an alcohol such as ethanol, isopropanol, or hexadecyl alcohol, glycols such as propylene glycol or polyethylene glycol, glycerol ketals such as 2,2-dimethyl-1,1-dioxolane-4-methanol, ethers such as poly(ethylene glycol) 400, an oil, a fatty acid, a fatty acid ester or, a fatty acid glyceride, or an acetylated fatty acid glyceride, with or without the addition of a pharmaceutically acceptable surfactant such as a soap or a detergent, suspending agent such as pectin, carbomers, methycellulose, hydroxypropylmethylcellulose, or carboxymethylcellulose, or emulsifying agent and other pharmaceutical adjuvants.

Illustrative of oils which can be used in the parenteral formulations of this invention are those of petroleum, animal, vegetable, or synthetic origin, for example, peanut oil, soybean oil, sesame oil, cottonseed oil, corn oil, olive oil, petrolatum and mineral oil. Suitable fatty acids include oleic acid, stearic acid, isostearic acid and myristic acid. Suitable fatty acid esters are, for example, ethyl oleate and isopropyl myristate. Suitable soaps include fatty acid alkali metal, ammonium, and triethanolamine salts and suitable detergents include cationic detergents, for example dimethyl dialkyl ammonium halides, alkyl pyridinium halides, and alkylamine acetates; anionic detergents, for example, alkyl, aryl, and olefin sulfonates, alkyl, olefin, ether, and monoglyceride sulfates, and sulfosuccinates; non-ionic detergents, for example, fatty amine oxides, fatty acid alkanolamides, and poly(oxyethylene-oxypropylene)s or ethylene oxide or propylene oxide copolymers; and amphoteric detergents, for example, alkyl-beta-aminopropionates, and 2-alkylimidazoline quarternary ammonium salts, as well as mixtures.

The parenteral compositions of this invention will typically contain from about 0.5% to about 25% by weight of the active ingredient in solution. Preservatives and buffers may also be used advantageously. In order to minimize or eliminate irritation at the site of injection, such compositions may contain a non-ionic surfactant having a hydrophile-lipophile balance (HLB) of from about 12 to about 17. The quantity of surfactant in such formulation ranges from about 5% to about 15% by weight. The surfactant can be a single component having the above HLB or can be a mixture of two or more components having the desired HLB.

Illustrative of surfactants used in parenteral formulations are the class of polyethylene sorbitan fatty acid esters, for example, sorbitan monooleate and the high molecular weight adducts of ethylene oxide with a hydrophobic base, formed by the condensation of propylene oxide with propylene glycol.

The pharmaceutical compositions may be in the form of sterile injectable aqueous suspensions. Such suspensions may be formulated according to known methods using suitable dispersing or wetting agents and suspending agents such as, for example, sodium carboxymethylcellulose, methylcellulose, hydroxypropylmethyl-cellulose, sodium alginate, polyvinylpyrrolidone, gum tragacanth and gum acacia; dispersing or wetting agents which may be a naturally occurring phosphatide such as lecithin, a condensation product of an alkylene oxide with a fatty acid, for example, polyoxyethylene stearate, a condensation product of ethylene oxide with a long chain aliphatic alcohol, for example, heptadeca-ethyleneoxycetanol, a condensation product of ethylene oxide with a partial ester derived form a fatty acid and a hexitol such as polyoxyethylene sorbitol monooleate, or a condensation product of an ethylene oxide with a partial ester derived from a fatty acid and a hexitol anhydride, for example polyoxyethylene sorbitan monooleate.

The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally acceptable diluent or solvent. Diluents and solvents that may be employed are, for example, water, Ringer's solution, isotonic sodium chloride solutions and isotonic glucose solutions. In addition, sterile fixed oils are conventionally employed as solvents or suspending media. For this purpose, any bland, fixed oil may be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid can be used in the preparation of injectables.

A composition of the invention may also be administered in the form of suppositories for rectal administration of the drug. These compositions can be prepared by mixing the drug with a suitable non-irritation excipient which is solid at ordinary temperatures but liquid at the rectal temperature and will therefore melt in the rectum to release the drug. Such material are, for example, cocoa butter and polyethylene glycol.

Another formulation employed in the methods of the present invention employs transdermal delivery devices (“patches”). Such transdermal patches may be used to provide continuous or discontinuous infusion of the compounds of the present invention in controlled amounts. The construction and use of transdermal patches for the delivery of pharmaceutical agents is well known in the art (see, e.g., U.S. Pat. No. 5,023,252, issued Jun. 11, 1991, incorporated herein by reference). Such patches may be constructed for continuous, pulsatile, or on demand delivery of pharmaceutical agents.

Controlled release formulations for parenteral administration include liposomal, polymeric microsphere and polymeric gel formulations which are known in the art.

It may be desirable or necessary to introduce the pharmaceutical composition to the patient via a mechanical delivery device. The construction and use of mechanical delivery devices for the delivery of pharmaceutical agents is well known in the art. Direct techniques for, for example, administering a drug directly to the brain usually involve placement of a drug delivery catheter into the patient's ventricular system to bypass the blood-brain barrier. One such implantable delivery system, used for the transport of agents to specific anatomical regions of the body, is described in U.S. Pat. No. 5,011,472, issued Apr. 30, 1991.

The compositions of the invention can also contain other conventional pharmaceutically acceptable compounding ingredients, generally referred to as carriers or diluents, as necessary or desired. Conventional procedures for preparing such compositions in appropriate dosage forms can be utilized. Such ingredients and procedures include those described in the following references, each of which is incorporated herein by reference: Powell, M. F. et al, “Compendium of Excipients for Parenteral Formulations” PDA Journal of Pharmaceutical Science & Technology 1998, 52(5), 238-311; Strickley, R.

The utility of the compounds of the present invention can be illustrated, for example, by their activity in vitro in the in vitro tumor cell proliferation assay described below. The link between activity in tumor cell proliferation assays in vitro and anti-tumor activity in the clinical setting has been very well established in the art. For example, the therapeutic utility of taxol (Silvestrini et al. Stem Cells 1993, 11(6), 528-35), taxotere (Bissery et al. Anti Cancer Drugs 1995, 6(3), 339), and topoisomerase inhibitors (Edelman et al. Cancer Chemother. Pharmacol. 1996, 37(5), 385-93) were demonstrated with the use of in vitro tumor proliferation assays.

The compounds and compositions described herein, including salts and esters thereof, exhibit anti-proliferative activity and are thus useful to prevent or treat the disorders associated with hyper-proliferation. The following assay is one of the methods by which compound activity relating to treatment of the disorders identified herein can be determined.

In vitro Tumor Cell Proliferation Assay

The tumor cell proliferation assay used to test the compounds of the present invention involves a readout called Cell Titer-Glow® Luminescent Cell Viability Assay developed by Promega (Cunningham, B A “A Growing Issue: Cell Proliferation Assays, Modern kits ease quantification of cell growth” The Scientist 2001, 15(13), 26, and Crouch, S P et al., “The use of ATP bioluminescence as a measure of cell proliferation and cytotoxicity” Journal of Immunological Methods 1993, 160, 81-88), that measures inhibition of cell proliferation. Generation of a luminescent signal corresponds to the amount of ATP present, which is directly proportional to the number of metabolically active (proliferating) cells.

A431cells (human epidermoid carcinoma, ATCC # HTB-20) and BT474 (human breast carcinoma, ATCC # CRL-1555) were plated at a density of 2.5×10³ cells/well in 96 well black-clear bottom tissue culture plates in RPMI media with 10% Fetal Bovine Serum and incubated at 37° C. Twenty-four hours later, test compounds are added at a final concentration range from as high 100 μM to as low 64 pM depend on the activities of the tested compounds in serial dilutions at a final DMSO concentration of 0.1%. Cells were incubated for 72 hours at 37° C. in complete growth media after addition of the test compound. After 72 hours of drug exposure, the plates were equilibrated to room temperature for approximately 30 min. Then, using a Promega Cell Titer Glo Luminescent® assay kit, lysis buffer containing 100 microliters of the enzyme luciferase and its substrate, luciferin mixture, was added to each well. The plates were mixed for 2 min on orbital shaker to ensure cell lysis and incubated for 10 min at room temperature to stabilize luminescence signal. The samples were read on VICTOR 2 using Luminescence protocol, and analyzed with Analyze5 software to generate IC50 values. Representative compounds of this invention showed inhibition of tumor cell proliferation in this assay.

For determination of IC50's, a linear regression analysis can be used to determine drug concentration which results in a 50% inhibition of cell proliferation using this assay format. The anti-proliferative activities of selective sets of compounds are listed below. In A431 cells, Examples 4, 15, 22, 26, 45, 54-55, 58-62, 66, 70, 72-75, 77-80, 82-88, 92-94, 96-98, 105, 139-142, 145, 148, 150, 152-154, 152-165, 167-171, 175-179, 183-186, 189-198, 200, 202-203, 205-212, 221-224, and 230 have IC50's below 5 μM; whereas Examples 1-3, 8, 12, 16, 20, 23, 24, 31, 32, 39, 40, 42, 46, 48, 49, 52, 56, 57, 63-65, 67-69, 71, 76, 81, 89, 90, 91, 95, 99-103, 136-138, 143-146, 147, 149, 151, 155, 156, 166, 172-174, 180-182, 187, 188, 199, 201, 204, 213-220, 225-229, 231-239 have IC50's below 50 μM. In BT474 cells, Examples 2, 4, 15, 22, 36, 39, 42, 43, 45, 45, 48, 54, 58-60, 62, 66, 67, 73-75, 77-80, 82, 84, 85-88, 92-99, 101, 103, 105, 136-143, 1148. 150, 152-200, 202-212, 214-239 have IC50's below 5 μM; whereas Examples 1, 3, 8, 12, 16, 20, 23, 24, 31, 32, 40, 49, 52, 55-57, 61, 63-65, 68-72, 76, 81, 83, 89-91, 100, 102, 144, 146, 147, 149, 151, 201, 213 have IC₅₀'s below 50 μM.

Based upon the above and other standard laboratory techniques known to evaluate compounds useful for the prevention and/or treatment of the diseases or disorders described above by standard toxicity tests and by standard pharmacological assays for the determination of the prevention and/or treatment of the conditions identified above in mammals, and by comparison of these results with the results of known medicaments that are used to treat these conditions, the effective dosage of the compounds of this invention can readily be determined for prevention and/or treatment of each desired indication. The amount of the active ingredient to be administered in the prevention and/or treatment of one of these conditions can vary widely according to such considerations as the particular compound and dosage unit employed, the mode of administration, the duration of treatment (including prophylactic treatment), the age and sex of the patient treated, and the nature and extent of the condition to be prevented and/or treated.

The total amount of the active ingredient to be administered will generally range from about 0.001 mg/kg to about 300 mg/kg, and preferably from about 0.10 mg/kg to about 150 mg/kg body weight per day. A unit dosage may contain from about 0.5 mg to about 1500 mg of active ingredient, and can be administered one or more times per day. The daily dosage for administration by injection, including intravenous, intramuscular, subcutaneous and parenteral injections, and use of infusion techniques will preferably be from 0.01 to 200 mg/kg of total body weight. The daily rectal dosage regimen will preferably be from 0.01 to 200 mg/kg of total body weight. The daily vaginal dosage regimen will preferably be from 0.01 to 200 mg/kg of total body weight. The daily topical dosage regimen will preferably be from 0.1 to 200 mg administered between one to four times daily. The transdermal concentration will preferably be that required to maintain a daily dose of from 0.01 to 200 mg/kg. The daily inhalation dosage regimen will preferably be from 0.01 to 100 mg/kg of total body weight.

Of course the specific initial and continuing dosage regimen for each patient will vary according to the nature and severity of the condition as determined by the attending diagnostician, the activity of the specific compound employed, the age and general condition of the patient, time of administration, route of administration, rate of excretion of the drug, drug combinations, and the like. The desired mode of administration and number of doses of a compound or composition of the present invention or a pharmaceutically acceptable salt or ester thereof can be ascertained by those skilled in the art using conventional prevention and/or treatment tests.

The compounds of this invention can be administered as the sole pharmaceutical agent or in combination with one or more other pharmaceutical agents where the combination causes no unacceptable adverse effects. For example, the compounds of this invention can be combined with other anti-hyper-proliferative or other indication agents, and the like, as well as with admixtures and combinations thereof.
